The cursed Polar Vortex…that semi-permanent area of low pressure that usually lives across northern Canada will, every now and then, head south. It’s occasional southward treks seldom comes this far south into so much of the continental U.S. But when it happens…like it is right now, the effects are dramatic. Hang in there. It will retreat on Wednesday and by Thursday temperatures will be back to average values again. But in the short term….WOW! The numbers in the forecast speak for themselves. There are going to be all kinds of record temperatures broken across the country for the next 48 hours. Our magic number is 5 degrees. That is the record low tomorrow morning officially in Washington. What is unusual is we are going to see the dramatically cold be accompanied by persistent, strong northwesterly winds. Usually, we achieve these very low numbers only when skies are clear and the winds are nearly calm.
